2.) During typhoon ambo PAGASA tracks the amount of the accumulating rain fall. For the first three hour's of typhoon that rain fell at a constant rate of 25 mm per hour. The typhoon slows down for an hour ad started again at a constant rate of 20 mm per hour for the next 2 hour's . Write a piecewise function that models the amount of rain fall as function of time. (this is for a friend)

Step-by-step explanation:

Given that :

First 3 hours, rain fell at a constant rate of 25mmper hour

Next one hour, tmrain slowed down

Next 2 hours, rate of 20mm per hour

Piecewise function which models the situation :

{25t ; t in range {0, 3)

f(x){75 ; t in range {3,4}

{75 + 20(t-4) ; t in range {4,6}

Hence, the function.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
